Just got mine installed and going but that damn memory training had me thinking something was wrong and the motherboard stating a ram error code didn’t help.
All good though, roll on nvidias release!

which gpu will you be getting?

It’ll be between the 5080 & 5090

Few days into my new pc build now. Had an issue but mainly due to my lack of experience (aka noob) with AMD hardware.
Pc posted first time into bios, didn’t take long to boot so all good so far. Enabled EXPO profile and installed windows and everything running fine apart from black ops 6 which randomly crashed after a couple of hours or so.
Tried everything: resetting windows, different nvidia drivers, running with nothing installed. No luck. Started to look at the error logs which were helpfully non descriptive but pointed to potential memory issues. Ran Memtest and errors galore.
Reseat memory, same. Try other slots, same. Eventually found a post that says you need to apply a setting in bios for UCLK = MEMCLK.
And now so far everything is fixed, no errors or crashes. So started to fiddle with CPU and have set curve optimizer -30 with a +200 boost clock override and seems solid. RAM is 6000 / CL30 so not sure if I can be bothered to mess around with it but may do later.

Laugh at what?
No chance. I’m getting one. Will probably see Halley’s comet make another pass before I get it in my hands though lol
There has to be a meaningful performance gain in the flagship or contempt will kill sales.
There isn't the same urge to spend 4 figures on a gpu if there's no FOMO. Plenty of people can burn money on tech but they need to be buying some happiness.
Results of testing 2133 vs 2200FCLK at 6400CL28
2133
2200
TLDR
2200 FCLK yielded around a 25-30pts improvement in CB24 and about 60pts in Timespy. Very slightly higher latency in AIDA64(0.3NS) but higher R/W/C figures. The gains in Black OPS 6 were actually quite significant, improving average frames by 24fps, and the 1% lows by 10FPS. Of course that isn't really percivable at these high frames, but it's an improvement nonetheless and more than I expected to be honest.
After testing in Linpack Extreme, I did see some GFLOP dip, meaning that 2200 was unstable at my previous VSOC of 1.27v. I was able to lower the VSOC to 1.18v and Linpack GFLOP throughput now seems consistent. Will need to retest RAM stability again, but suspect it should be fine.

They won’t
Wouldn't care if they did tbh. Wasn't remotely tempted by the other 3D offerings last time.
Also not sure why but my pc takes 20x longer to boot up now than it did before. I see by the mobo led it's doing memory training but thought that was a one time thing.

I can buy the 5090 - but if the pricing is stupid - I'll skip just to send a message to Leather man

2200 is not stable, try 2167. Aida latency should go down, if it goes up or stays the same FCLK needs to be dropped.Results of testing 2133 vs 2200FCLK at 6400CL28

In general or for me personally? Isn’t it typical to see a slightly higher latency when raising FCLK past 2133?
I have lowered the VSOC from 1.27v to 1.18v and the GFLOP figures in Linpack are consistent. Testing with P95 Large FFT’s now. Currently at 1 hour with no errors.

As far as I know, raising FCLK will also increase latency, but in turn, increase bandwidth. I think it is typical to see a slight latency increase when going from 2133 to 2200. It does not mean it isn’t stable.
Unstable FCLK is hard to test for, but fluctuating GFLOP throughput on Linpack report is one sign. I was getting throughput drop at 1.27v VSOC, but am not at 1.18v. Testing Large FFT on P95 is also another way to test FCLK stability as it is very hard on the IMC. No errors at one hour.
